Criminal justice client rehabs are available as being a considerably better option than incarceration or significant fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, someone who has been in prison for driving drunk of alcohol or drugs may qualify for treatment services for problem as an alternative to serving time in jail. The judge might order that the individual receive treatment, either alone or together with other consequences. Very first time offenders in particular tend to be given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehab have better probability of remaining out of the system after treatment.
